Will Stackable rebuild this script?

Migrating a discounted cart subtotal script

Two scripts can look identical here and mean opposite things. One measures what its own earlier lines left behind; the other measures what somebody else’s discount left behind, and only the second is out of anyone’s hands.

Hvad dette Script gjorde

It subtracted the shopper’s discount code from the subtotal first, then compared what was left against its threshold.

Hvad der sker med denne

Shopify cannot do this at checkout

Your Script measured its threshold against a subtotal that another discount had already reduced. Discounts at checkout all run at the same moment and cannot see each other's work, so we only ever see the original amounts.

Det her er en begrænsning i Shopify og ikke et hul i Stackable. Ingen rabat-app kan genopbygge det i dag, og derfor peger linket nedenfor på Shopifys egen dokumentation og ikke på vores.

Der er ingen kurv at teste her, fordi der ikke bliver bygget noget. At indsætte det her giver beskeden ovenfor og slet ingen kampagne.
